An auto-identification system is described that includes a plurality of distributed auto-id nodes that are operable to track physical objects as they move through an operation of an enterprise, such as, for example, a supply chain network or a sales network. The auto-id nodes are distributed across sites of the network, and are in communication with enterprise application systems and/or data acquisition systems such as RFID readers or sensor devices. By focusing on their respective sites, the auto-id nodes minimize the amount of data tracked by their respective enterprise applications. Further, the auto-id nodes include rules governing operations on the physical object(s). When an auto-id node receives information regarding a tracking event experienced by the physical object, then the rules may be executed to access known data regarding the physical object, and thereby determine whether the tracking event matches an event that was expected to occur as a result of the operation of the enterprise.
